Name: Rubber Sewage Check Valve
Rubber is also called rubber duckbill check valve discharge valve, duckbill check valve rubber, rubber flexible check valves, slow closing check valve rubber. Xf rubber slow closing check valve is an all-rubber structure, in shape, "beak-like" with "forward flow, reverse backstop" features of the new water supply and drainage valves. It is based on mechanical analysis and stress calculation for different conditions, using different design mechanisms, use different rubber formulations, made according to special technology. Positive work, the water flows from the inlet, small water pressure, can open the valve, the greater the pressure, the greater the valve open, the greater the water flow, valve port is tightening, and good sealing effect. It is widely used for municipal, water, sewage and other effluent discharge, to prevent intrusion, back, is the ideal product to replace door.
Rubber Sewage Check Valve Features
I have more traditional film, particularly evident advantages:
1, according to water pressure automatically open and close, safe and reliable, no noise, no personnel to operate, no maintenance.
2 forward on the water resistance is small, start-up pressure is small, and the natural flow regulation under pressure:
3 Reverse Check sealed, no leaks, prevent backflow, back pressure the greater the effect the better:
4 anti-corrosion, anti-aging, deformation, adaptability, long life;
5 sizes a wide range of nominal diameters DN50 to DN3000.
Scope of the sewage check valve rubber
1 The product performance, use a wide range of
2 used in the sewage system
3 selected for drainage system
4 used in the dam discharge
5 used in airports, highways, drainage
6 used in the sewer discharge
7 used in the discharge of sewage pond

Rubber discharge valve installation instructions
1 Preparing for Installation
2 Please check the conditions on the valve type, installation, technical parameters, technical requirements (pressure or North pressure, temperature, corrosion-resistant conditions) are consistent.
3 Check whether the people inside and outside the damaged valve, check valve and whether the stolen goods.
4 Check the installation or the outer surface of pipe flange connections with or without spikes, with or without deformation, is smooth.
5 installation process
6 socket rubber sewage check valve installation should be connected to the valve diameter and the diameter of the pipeline right match; set into the depth should be consistent with the corresponding requirements; plus hydraulic pipe surface can be coated with rubber seals; clamp mount should be appropriate to add a rubber gasket between, and then tighten the bolts; slow closing check valve if the use of rubber auxiliary liner, connection, auxiliary liner and seal weld pipe should be set aside and appropriate increase in gluten strength and improve rigidity.
7. Flange rubber check valve installed sewage, drainage outlet flange size should slow closing check valve with rubber connection to the corresponding flange dimensions; flange between the flange and the specific circumstances of the examination, the installation of sealed pad to ensure the connections are tight after the absolute seal; must be careful not to break something slow closing check valve rubber flange lips.
8 other installations, the reference to the above requirements
9 When the nominal diameter greater than DN800, due to the larger body weight, combined with work, there are a lot of abdominal body of water and water impact, the need to increase a supporting rod through the rings on the body, the body long-term solid lift.
10 Notes
11 body in the handling, storage, installation, to avoid non-standard operations.
12, such as body long-term preservation, to prevent fire. Non-stacked.
13. Normal use, no maintenance, but to expose the body to prevent the sharp hard objects.
14 work sites can not have objects of extrusion, so as not to affect its nature open and close.
Ordering Information
1 user to provide on-site conditions of use case description and technical requirements.
2 user to provide the necessary technical parameters, including the nominal pipe diameter, pipe diameter interfaces, installation type and a positive opening pressure, reverse Check back pressure values.
3. Our technical staff will be based on the user's requirements, selection and design of the user.
XH81, XH41, XH81A, XH41A rubber Sewage Check Valve (Spain called "flexible duckbill check valve" called the U.S. "duckbill valve rubber flat mouth") is a valve company in Spain ROSS, American Red Valve Company production based on the summary, exemplary. Revolutionary re-design. More committed to continuous improvement (duckbill check valve flexible) rubber discharge valve, leaving the valve of the strength, toughness, sealing significantly increase business, the valve does not have any active components. Free repairs. The valve can give straight pipe, flange pipe, concrete pipe, glass pipe support, the valve is widely used in coastal, beach, docks, reservoirs, municipal drainage, sewage. Can be described as environmentally friendly green valve, check valve door to replace the valve. Easily solve the door sand, silt, rocks, vegetation, marine life blocking problems.
